STREET-INDICATOR.

Specicaton of Letters Patent.

Patented July 7, 1914.

Application filed october 14,1913. serial No. 795,093.

To all whom t may concern Be it known that I, GEORGE OKUYAMA,'a Japanese subject, residing at Madison, 1n the county of Dane, State of Wisconsin, have invented certain new and useful Improvements in Street-Indicators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to street yindicators for railway cars and has for an Object t0 provide a novel mechanism for transferring a band step by step from a supply roll to a receiving roll in such a manner as to bring fresh parts upon which the streets are printed to view.

A further object of the invention is to provide a device of this character which will be inexpensive to manufacture, strong and durable in construction, and will be formed of a few parts that will not easily get out of order.

With the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claims.

In the accompanying drawing illustrating this invention :-Figure 1 is a front elevation of the device. Fig. 2 is a side elevation of the device. Fig. 3 is a longitudinal sectional view of the device taken on the line 3-3 Fig. 2. Fig. l is a cross sectional view of the device taken on the line. 4--4 Fig. 3. Fig. 5 is a cross sectional view of the device taken on the line 5`-5 Fig. 2.

Fig. 6 is a fragmentary sectional view show-l ing the position of the cord when the band supply has been taken up by the receiving roll.

Referring now to the drawing in which like characters of reference designate similar parts, the device is shown to comprise a casing 10 within which is supported a supply roll .11 and a receiving roll r12, the rolls being journaled one above the other and having their respective shafts 13 and 14 projecting at one end .through the casing and there being equipped with respective retarding springs 15 and 16 for preventing too free rotation of the rolls. upon the supply roll and is trained for- A band 17 1s wound.

wardly and downwardly over guide rollers I whereby to successively bring into registration with'the sight glass the names of the various streets at which the railway car makes stops. f f

.For actuating the receiving roller I provide a ratchet lever 21 that is pivoted on a stub shaft 22 outside ofthe casing, the stub shaft extending into the interior of the casing and being equipped therein with a gear 23, the ratchet lever carrying a spring pressed pawl 24: which operatively engages a ratchet wheel 25 on the stub shaft. Said gear 23 meshes with a pinion 26 carried on the shaft 27 of a drum 28 which is cylindrical in outline and is provided spirally with a cord receiving groove 29. Fixedv on the receivingroll is a drum 30 which is frustoconical in outline, that is, it tapers from the receiving roll toward the adjacent end of the casing, and is provided with a spiral cord receiving groove 31 within which a cord 32 is wound, the free end of t-he cord being directed from the smaller end of the drum up to the overlying end of the cylindrical drum 29 and secured in the groove of the lat-ter.

A. cord 33 is attached to the ratchet and forms means whereby the car conductor may rock the ratchet lever whereby to actuate the drum 29 and wind the cord thereon from the drum 30 whereby the latter is rotated and rotates the receiving roll 12 which winds thereupon the band 17. Since it is necessary to provide that a uniform length of the band be passed at each .step actuation of the lever` In operation the conductor will pull thev cord 83 just after the car leaves a street where has made a stop so that the printed naine of the street Where the `next Shop is made is advanced into registration with the sight glass and may be viewed by the pas- It is obvious that other printedr sengers. matte-r besides the names of streets may be displayed on the band Without departingv from the spirit or sacrificing any of the ad= Wound upon said -supply roll and secured to 'be taken np by said receiving roll, a ratchet and pavvl actuating means, 'a cylinv drical drum having a spirally grooved pefrusto-oonicai drum on the shaft of said receiving roll having` the large end directed toward said receiving roll, said rusto-conical drnin being provided vvithwa spiral groove, a cord Wrapped about said f-rustoconical `dra-inl ysaid groove and being directed from the small end of said drum and secured in the groove :0f Said cylindrical drum, said ,00rd being Wound upon sald Cylindrical drum during actuation, thereof and serving :to rotate said receiving roll through v aconstantly increasing arc .of movement at each sten aotuation, y
